Tire 97w refers to the load index of the tire, where 'w' represents the speed rating of the tire. The speed rating indicates the maximum speed at which the tire can carry a specified load under defined conditions. Tires are one of the most important components of a vehicle, directly in contact with the road surface and working in conjunction with the vehicle's suspension to absorb shocks during driving, ensuring good adhesion between the wheels and the road, and improving the vehicle's traction, braking, and off-road capabilities. Precautions for using car tires include: 1. Pay attention to the degree of tread wear; 2. Avoid excessively high or low tire pressure; 3. Remove debris from the tread to prevent punctures that could lead to air leaks or blowouts; 4. Regularly rotate tires to prevent uneven wear.

Will Insurance Cover a Car Flooded in a Flood?

If you have purchased water wading insurance, the insurance company will compensate. Here is additional information: 1. Engine water ingress: General losses from a flooded car can be compensated within the limits of the vehicle damage insurance, but most insurance companies' vehicle damage insurance policies include exemption clauses for 'losses caused by engine water ingress.' Compensation for damages caused by engine water ingress can be complicated and may even be denied. 2. Water wading insurance: Water wading insurance is an additional coverage that cannot be purchased separately and must be bought alongside vehicle damage insurance. If you have already purchased vehicle damage insurance, you can add 'water wading insurance' at the insurance company. This insurance has a 20% deductible rate, but if you purchase the no-deductible option for this coverage, you can receive 100% compensation.

What is the difference between engines that use 95-octane and 92-octane gasoline?

The difference between engines that use 95-octane and 92-octane gasoline lies in the compression ratio: engines using 95-octane gasoline have a compression ratio between 10.0 and 11.5, while those using 92-octane gasoline have a compression ratio below 9.5. The choice of gasoline octane rating should match or be compatible with the design of the car's engine. Vehicles with higher engine compression ratios should opt for gasoline with a higher octane rating. 95-octane gasoline, which has a higher octane value, is suitable for engines with higher compression ratios. In such engines, as the operating speed increases, the ignition timing in the cylinder advances. When the speed reaches a critical point, the air-fuel mixture in the cylinder may ignite prematurely before the spark plug fires, a phenomenon known as knocking. Increasing the octane rating of the gasoline effectively enhances its anti-knock properties.
